SUMMARY 

Whenever I bring my TV-B-Gone out to restaurants, I look suspicious pointing it around. 
Mitch Altman, the device's creator, concealed his by putting it inside a hat (see the TV-B- 
Gone Hat project), but I rarely wear hats and wanted a more subtle and dinner-appropriate 
solution. 

So I bought a zippered hoodie sweatshirt from a thrift store and turned it into a wearable TV 
silencer. For the switch, I sewed paths of conductive thread to 2 little pads that are bridged 
by the metal zipper pull when it passes by, so all I have to do is zip the sweatshirt up or

down to activate the TV turning-off action. It works great, and you can just unsnap the 
circuitry to convert it back into a normal sweatshirt for washing — or for avoiding trouble. 



Step 1 — Mount the circuit board onto the fabric swatch. 




• Assemble your TV-B-Gone according to the kit instructions , but omit the push-button 
switch, and mount the 4 infrared LEDs perpendicular to the printed circuit board. 

• Solder short wires to 2 of the 4 holes for the switch in the PCB. Pick the 2 that are visibly 
connected to the rest of the circuit. Strip the other ends and solder each to one half of a 
sewable snap. In the same way, attach 2 short wires to the board's power connections and 
snap halves; these will connect to the battery holder. 

• The fabric swatch will sandwich the circuit board to the hoodie and protect your skin from 
any pokey metal bits. Position the PCB in the middle of the swatch and use regular thread 
to stitch the 4 wired snaps along the swatch's corners and edge. 

• Also stitch the wires and the board itself onto the swatch; I looped thread around 
component leads and through holes in the board, and reinforced the LED leads with hot 
glue. 

• Finally, stitch 2 more snap halves onto the 2 empty corners, just for holding the other side 
of the swatch. Check that your TV-B-Gone still works properly by bridging the switch 
snaps with a piece of wire.

Step 2 — Attach the swatch and stitch the traces. 




• Position the TV-B-Gone swatch under the sweatshirt and use an awl to poke holes through 
the fabric for the 4 infrared LEDs. Mark the positions of the 6 snaps on the inside of the 
sweatshirt. 

• Referring to the project schematic, stitch conductive thread traces from the 2 switch snap 
positions to the edge of the zipper, making sure they never cross. Leave long tails of 
conductive thread at each end for hand-sewing the snaps and switch. 

• Insulated wire works better and is safer than conductive thread for supplying power, 
so solder 2 stranded wires to extend the length of the battery holder leads, and 
insulate the joints with heat-shrink tubing. Place the battery holder in the pocket and run 
the wires up to the power snap locations. Tack the wires in place with regular thread.

Step 3 




• Use the conductive thread to sew 
the 2 remaining switch snap halves 
in position inside the sweatshirt, 
matching their positions on the 
swatch. Solder the 2 remaining 
power snap halves to the battery 
wires, then use regular thread to 
sew them into the sweatshirt. 

• Finally, use regular thread to sew 
the last 2 unconnected snap halves 
at the other end of the swatch.

Step 4 — Stitch the zipper switch. 




• Stitch the zipper switch. Thread your needle with the conductive thread tails near the 
zipper, one at a time. Stitch 2 little pads right next to the zipper, close enough to each 
other to be bridged by the zipper slider. Sand any paint off the metal zipper slider 
anywhere it will come into contact with the thread. 

• Your TV-B-Gone hoodie is machine washable; just unsnap the circuit and remove 
the batteries beforehand, and let it dry completely before replacing them. You could 
even make the battery pack removable, by connecting it with metal snaps, too.
